Identification and quantification of regional brine and road salt sources in watersheds along the New York/Pennsylvania border, USA

Setting the baseline for shale gas – Establishing effective sentinels for water quality impacts of unconventional hydrocarbon development

“…a further determinand could be to the analysis. Johnson et al (2015) have suggested that sources of brine in areas of unconventional hydrocarbon extraction could be distinguished bu use of Cl/Br ratio; Sr isotopes or the ratio (Ba + Sr)/Mg. Indeed, Wilson and Van Briesen (2013) used Cl/Br ratios to detect shale gas fluids in surface waters of the Mononghela river in Pennsylvania.…”

Fingerprinting Marcellus Shale waste products from Pb isotope and trace metal perspectives

“…For method details see Johnson et al (2015). The average % Relative Standard Deviation (% RSD) for analytical results from the ICP-OES was typically less than 5%, and typically less than 2% for the IC analyses.…”

“…Most research to date has focused on the spatial and temporal variability, transport, disposal, origin, and fingerprinting of environmental impacts from flowback and produced waters (e.g., Chapman et al, 2012Chapman et al, , 2013Barbot et al, 2013;Ferrar et al, 2013;Lutz et al, 2013;Schmidt, 2013;Shaffer et al, 2013;Warner et al, 2013;Kolesar Kohl et al, 2014;Vengosh et al, 2014;Johnson et al, 2015). Less attention has been focused on the disposal of drill cuttings, which are produced during vertical and horizontal drilling processes.…”

Identification of Mass Transfer Parameters for Rock Salt Dissolution in a Plug Flow System

“…The feasibility of solution mining is sustained by the fact that the operation at Ocnele Mari cashed 1.3 millions € which fully covered the cost of the drillings and pipe system necessary to transport the brine [2]. Also, salt solution mining is applied on large scale in the USA where just in New York state 241 wells produced more than 7 million m 3 of brine in 2014 for evaporating and chemical manufacturing [4].…”
